CARQ-TRUCK.

SPECIFICATION forming part of Letters Patent No. 291,582, dated January 1, 1884.

Application filed September 10, 1883. (No model.)

To (ZZZ whom it may concern.-

Be it known that I, \VILLIAM I-I. MONTZ,

.of Lehighton, in the county of Carbon, and in the State of Pennsylvania, have invented certain new and useful Improvements in Trucks for Railway-Cars; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which-,

Figure 1 is a side elevation of a truck containing my improvements. Fig. 2 is an end elevation, partly in section, of the same. Fig. 3 is a plan view of the bolster detached from the truck. Fig. at is a side elevation of the same, and Fig. 5 is a perspective view of the cap separated from the bolster.

Letters of like name and kind refer to like parts in each of the figures.

. are combined the cap, bolster, and frame, substantially as and for the purpose hereinafter shown.

In the use of the cartruck shown in the annexed drawings-known as the Diamond Trnckit has heretofore been customary to employ a woodenbolster, which, in conse quence of its lack of strength, would spring downward and allow the car-body to rest upon the side bearings of the truck, and thus destroy the center-bearing characterof the latter.

In place of the wooden bolster described, I employ a metal bolster composed of a straight jfiat bar of metal, A, and an arched metal bar,

B, of like or smaller size, which bars are connected together at their ends by welding,

a bolts, or other like means, and at or near their longitudinal centers are connected and held in relative vertical positions by means of posts 0, that are placed between the same, and bolts D, which. pass vertically through said bars and posts and through a center plate, E.

At suitable points near the ends of the bolster I place side bearings, F, which are secured in position by means of bolts G, that pass vertically through said bearings, the

plates A, and through interposed posts or thimbles H. 4

In connection with each end of the trussed bolster described, I employ a cast-metal cap, I, which has the general form shown in Fig. 5, and is provided with a horizontal recess, 2', that corresponds to and receives the end of said bolster, to which end said cap is screwed by means of two bolts, K, thatpass vertically through said parts. The cap I fits between the arch-posts L of the frame and rests upon but when used with cars having greater ca pacity than that named a truss rod, N, is placed upon each side of said bolster, with its ends passing through lugs f, that are cast upon the side bearing, F, and its central portion extended beneath a post, 0, which extends downward from the center of the barA or from the central post, 0.

The construction of bolster and cap shown materiallyincreases the strength and durability of the truck, and enables the same, with out other change, to be adapted for use heneath cars having any desired carrying capacity.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1s 1. As a means for connecting the bolster with the truck-frame, the cap I, having the form shown, and provided with the recess '5 and side flanges, t, substantially as specified.

2. As an improvement in car-trucks, the hereinbefore-described bolster, composed of the bars A and B, connected together at their ends, and having their centers united and held In testimony that I claim the foregoing I io in relative vertical positions by means of the have hereunto set my hand this 24th day of posts 0 and bolts D, in combination with the May, 1883.

truss-rods N, substantially as and for the purpose shown. WVILLIAM H. MONTZ.

3. The hereinbefore-described car-truck, in

which the trussed bolster, cap, and frame are Vitnesses:

constructed and combined in the manner and THOMAS C. BECK,

for the purpose substantially as set forth. 5 GEO. S. PRINDLE.
